Which task results in rendering enemy personnel incapable of interfering with an operation?

The task that results in rendering enemy personnel incapable of interfering with an operation is neutralize. This term specifically refers to actions taken to eliminate or incapacitate enemy forces to the extent that they can no longer pose a threat to friendly operations. Neutralization is critical in achieving a clear operational advantage, as it ensures that enemy personnel cannot engage or hinder friendly forces during a mission.

In contrast, other tasks such as delay, disrupt, or suppress may have different implications. While they can achieve temporary setbacks for the enemy, they do not guarantee that the personnel are rendered completely incapable of interfering. For instance, delaying may slow them down, disrupting might cause confusion, and suppressing involves limiting their ability to respond effectively but doesn't necessarily incapacitate them completely. Thus, neutralizing enemy personnel is the most effective way to ensure operational success and safety.
